Analysis and monitoring of drought temporally and spatially using MODIS sensor products (Case study of Isfahan province)

Pages 17-27

Drought is a natural hazard that has a significant impact on the economic, agricultural, environmental and social aspects. Therefore, monitoring and studying this phenomenon is important and vital. Much research has been done in this regard and based on indicators extracted from satellite data. In the present study, drought monitoring was performed based on the VHI index extracted from satellite data. This index is a combination of two indicators of vegetation status (VCI) and temperature index (TCI), which is used to calculate these two indicators of MOD13 and MOD11 products of MODIS sensor, which are related to normalized differential vegetation index (NDVI) and surface temperature, respectively. Land (LST), used in the period from 2010 to 2018. Evaluation of telemetry index (VHI) was done using standardized precipitation index (SPI), so that the correlation coefficient of annual values of SPI index, 14 synoptic stations of the study area with VHI index values in the same stations in the period 2010-2017 شد .The results showed a correlation coefficient between 0.64 and 0.81 in the years under review.

Evaluation of evaporation pan coefficients for empirical methods to Estimate Reference Evapotranspiration

Pages 47-59

Reference evapotranspiration (ETo) is one of the main parameters in water resource planning and water management. Pan coefficient Class A (Kp) is an important factor for calculation of reference evapotranspiration (ETo). There are several ways to estimate Kp using different parameters such as wind speed, relative humidity and vegetation. In this study, using daily meteorological data for 4 years period from Shahrekord Meteorological Station using different equations such as Cuenca, Allen Pruitt, Snyder, Orang and Pereira, pan coefficient was estimated. Then, those values were estimated FAO-Penman-Monteith, Penman-24, Turk, Blaney-Cridle and Hargreaves-Samani equations. Results were comprised to lysimeter data collected from this region. Also for choosing the best model, between three parameters, Root mean square error, Mean absolute error and Standard Estimation Error rank test was performed. Results showed that pan evaporation methods had better accuracy compared to empirical methods. In addition, Turk equation ranked as the best and most accurate method and Penman-24 was the worst one.

The sedimentary of estimated with (SRD) method in Sanghaneh kallat basin (northeast of IRAN)

Pages 60-69

Soil erosion and sediment transport to waterways are among the most important environmental problems and concerns in sustainable development and play an important role in formulating watershed management strategies. Knowledge of sediment delivery ratio is important for effective implementation of soil conservation and watershed management programs. In this regard, choosing the appropriate model for estimating sediment delivery ratio can be an appropriate tool for calculating erosion amount to implement erosion control and containment programs in the watershed. The erosion and sediment measurement plots have been installed at Kalatan Sangat Research Station since 2006 and during this time the exclosure area has been enclosed and all data recorded accurately after each thunderstorm and rainfall. In this study, 10 experimental models of sediment delivery ratio estimation were compared with real data recorded at Sanganeh station. The results showed that Williams model with relative error of 19.72% is the most suitable method for estimating SDR in Kalanat area in Khorasan Razavi province with semi-arid to dry climate.

Socio-cultural indicators affecting The presence of children aged 0-14 years in public spaces of Shandiz

Pages 89-101

Today, public spaces in cities are shaped by the standards and needs of adults. And these spaces often lack appropriate and safe standards for children, while measures such as the creation of the World Convention on the Rights of the Child, the project of child-friendly cities are underway. The aim of this study was to investigate the socio-cultural indicators affecting the presence of children in public spaces outside the service area of Shandiz Municipality. The statistical population of this study is children aged 0-14 years old living in Shandiz city based on the 2016 population and housing census and their parents. Using the Cochran's formula, the completed sample size of 350 children-parents were interviewed. This research is of applied type and its method is descriptive-analytical and non-parametric statistical methods have been used to measure and analyze the questionnaires using SPSS software. The results show that the value of correlation coefficient for the three factors of participation, security of social order is equal to 0.201, 0.247 and 0.116, respectively. Therefore, the quality of the above socio-cultural indicators is directly related to the presence of children in public spaces, which according to the citizens of public spaces in Shandiz, have a low and very low level of security, social order and participation in programs.

CNG Fuel Location potential of Ahvaz Using Decision-Making Models and Geographic Information System

Pages 132-150

Sustainability of the projects is the major concern of developing in developing countries. It has been evident that development activities have a high potential to cause damage to the environment. The rapid growth of urbanization has led to more demand for vehicles, leading to more fuel consumption. Fuel location is one of the important centers, but at the same time, it is considered a hazardous facility. Choosing the right place for these facilities requires special attention at the initial stage of the project and is one of the most important aspects of success for any commercial project. Therefore, the main objective of this research is to find the location of natural gas fuels using GIS and decision making models in Ahwaz. The nature of the research applied theoretical and its method of study is descriptive-analytical. To achieve this goal, the map of effective criteria for locating the location of natural gas fuels such as road network, residential use, education, etc. was provided in ARC / GIS software. The Shannon entropy method and Suara method were used to determine the weight of criteria and prioritization and to determine the relationships between variables. Finally, by weight multiplication of each criterion in the prepared layer for each criterion and overlaying the layers, a final map of the appropriate locations for building fuel in Ahwaz city was prepared. The results of the final map indicate that the 1st and 5th regions lack fuel cell and these areas have the highest priority for the construction of new fuel stations. Then the Vikor method was prioritized between Ahwaz city areas. The results of this study show that the application of GIS spatial analysis as well as the Swara model, along with the Vikor model, makes more accurate the results of the decision and provides more precise location options.

Keywords: Location of CNG fuel, spatial information system (GIS), Swara model, AhvaZ
